PATENT CHARLES L. PEIRCE, JR, OF CHICAGO, ILLINOIS.

COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent N 0. 716,274, datedDecember 16, 1902.

Application filed May 26, 1902.

Serial No. 109.893. (No model.)

To all whom it may concern:

Beitknown that I, CHARLES L. PEIRCE, Jr. a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and use- I around said bolts as the same areinserted in the holes made therefor; and it consists in certainpeculiarities of construction and combination of parts, as will be fully set forth hereinafter in connection with the accompanying drawingsand subsequently claimed.

In the said drawings, Figure 1 is a view in side elevation and partly insection of one form of my said tool. Fig. 2 is a partly-sectional viewillustrating another form of the tamping end of the same. Fig. 3 is anend view of the opposite end of the tool, partly in section, on the line3 3 of Fig. 1. Fig. 4c is a partly-sectional view drawn to an enlargedscale and illustrating the tamping operation.

My said tool is particularly designed for use in connection with theexpansible bolt-fastening devices which form the subject of my priorapplication for Letters Patent, Serial No. 93,378, filed February 10,1902, and illustrated in Fig. {lof the present drawings, and with thissingle tool all the operations of drilling and tamping can beaccomplished, as

hereinafter explained.

Referring to the drawings, or represents a section of brickwork, stone,or other masonry having a hole I) drilled therein, in which is inserteda bolt 0, whose head is surrounded by a soft-metal collar or sleeve 01,all as shown in my said prior application for Letters Patenthereinbefore referred to and herein illustrated in Fig. 4: of thepresent drawings.

Referring now especially to Fig. 1, e represents a rod, preferablycylindrical in form, to one end of which is secured a sleeve or collarf, with solid central portion and tubular end, forming a chuck for thereception of the shank g of a drill.h or analogous tool. This shank g isformed with a socket v therein for the reception of a pin-j, projectinginwardly from a pointadjacent to one end of a fiat spring is, whoseother end is secured to thesaid sleeve f by a pin on passingtransversely through the spring 7c and sleeve f, which latter istransversely bored for the passage therethrough of the said pin, thesaid pin m beingkept in place by swaging the metal thereof, as shown,thereby securing the sleeve or collar f to the rod e and the spring tothe said sleeve or collar, the pin on further serving as a handguard inthe use of the tool, as hereinafter described, the pinj passing througha holein the part f and into the socket t'. Loose on the rod e is asliding double-ended hammer n, and the end of the rod opposite to thatcarrying the drill is tubular or formed with a longitudinal bore, asshown at 0, so as to receive the shank of a bolt 0 in the tampingoperation, as hereinafter described. In the form of my deviceillustrated in Figs. 1 and 4 this tamping end of the tool is providedwith a collar p, shrunk, brazed, or otherwise secured to the rod e; butin Fig. 2 in place of the collar 13 I have shown a sleeve or collar qsimilar in construction to the hereinbefore-described drill-sleeve f atthe other end of the rod, and in this form a of construction (shown inFig. 2) the adjacent end of the rod 2 terminates within the sleeve q,and the socket o of the tamping end is formed in a rod-section r,constituting a chuck for the tamping-tool, this part 1" being formedwith a socket s therein and held in place by a pin 25 on a flat springa, the said spring being secured to the sleeve q and rod e by a pin 12passing through the said spring, sleeve, and rod and being swaged, likethe pin m, already described, the pin 23 passing through a transversehole in said sleeve and entering the socket s in thesaid rod-section r,the pin 2; likewise forming a hand-guard. The object of the constructionset forth in Fig. 2 is to enable the tool to be used with a series ofrod ends 1', having bores otherein of different diameters so as to fitdifferent sizes of bolts when desired, and similarly the other end isadapted for the reception of a series of drills h or other tools ofdifferent sizes, both parts 1' and it having the same-sized shanks.

The operation of my device will be readily understood from the foregoingdescription of the same, taken in connection with the accompanyingdrawings. When a bolt 0 is to be secured to masonry, the drill end ofthe tool is held against the brick, stone, or other material of whichthe masonry is formed and the sliding hammer reciprocated, With itsoperative end to striking against the adjacent end 00 of the sleeve f,the rod e being turned, if desired, from time to time to vary thecutting edge of the drill 71. When the hole I) has been formed theproper depth in the masonry a, the bolt 0, with its head surrounded bythe described soft-metal collar or sleeve d, is pushed into the saidhole I) and the tool reversed, With the tubular end 0 of the rodsurrounding the shank of said bolt, and then the sliding hammer n isagain reciprocated, with its other operative end 1 striking against theadjacent end ,2 of the sleeve 29 (or collar q, as

the case may be,) thereby tamping the soft metal and spreading the samewithin the hole b, and thus securing the said bolt 0 firmly in place.Thus, as stated, with this single tool all the necessary operations canbe properly andquickly accomplished, resulting in a considerable savingin time and trouble, together with a great addition to the convenienceof the operator.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A combination-tool, comprising a rod having sleeves or collarssecured to its opposite ends, and tools projecting beyond said sleevesor collars, in combination with a sliding double-ended hammer mounted onsaid rod intermediate of its ends.

2. A combination-tool, comprising a rod having a longitudinal bore inone end, projecting beyond a sleeve or collar fast on said rod, and adrill-holder formed with a sleeve or collar secured to its opposite end,in combination with said sleeve or collar and an intermediate slidingdouble-ended hammer.

In testimony that I claim the foregoing I 1 have hereunto set my hand,at Chicago, in

the county of Cook and State of Illinois, in the presence of twowitnesses. CHARLES L. PEIROE, JR.
